telephone rings

Me: Clinic, this is T----, how may I help you?
Caller: This is ------from --------pharmacy. I am calling to follow up on a refill authorization request we sent on August 28th.
Me: All right.
Long silence
Caller: Do you need the patient's name?
Me: (what i really said). Yes I do, I can't help you if I don't know who you are calling about?

What I wanted to say---NO, you stupid f***, let me guess. We only have 1200 patients here, shouldn't take long too whittle it down to the one you are calling about, you idiot.

Really!!!! Five o'clock can't come soon enough today.
